Welcome to the Metrozone

Unlock the door

You inspect the lock, and try all the keys that might fit. Twice. But nothing works, and you have to abandon your attempt. The light’s going to have to stay on.

You make your way back to the lift area and check the other big room. Again, apart from the stacked furniture, there’s nothing to see. You use the small door in the stud wall to get back to the stairs.
